Descriptions:

The Fabspeed Long Tube Race Headers for the 718 4.0L cars deletes the factory catalytic converters and impressive power gains across the board. Our design process started with 3D scanning the entire exhaust system using our CREAFORM 700 HandySCAN so that we could make a complete Solidworks 3D model of the exhaust. We then designed the exhaust and fixtures using that model so that the exhaust fit perfectly to OEM standards. After revisions for sound and dyno testing we settled on using 1 7/8 inch primary's compared to the smaller 1 3/4 inch factory primary's. The primaries are mandrel bent using CAD designed model that allows us to achieve the optimal primary length and bends for best flow and scavenging at the collector. The flanges are thick 304 stainless steel that are CAD designed to perfectly match the cylinder heads and reuse the factory metal gaskets.

Sound:

With PSE off our Race Headers give a noticeable increase in exhaust volume with absolutely no interior drone. With PSE on, that's when the "Race" in Long Tube Race Header comes into play. The 4.0L's exhaust note sounds much closer to a Porsche GT3 Cup Car with that raw flat 6 sound and sharp deceleration crackle. If you need to cut down on how loud your exhaust is because of race track rules, we sell turn down tips which cut 3-6db of exhaust SPL.

Power:

These headers will add more power than any other single bolt on part. Significant gains can be seen throughout the entire RPM band. On our DynoJet we saw +24 whp and 26 ft/lbs of tq at 7,700 RPM and strong torque gains down low with gains of +26 ft/lbs of tq at 2,600 RPM and 21 ft/lbs of tq at 4,600 RPM. This is power that you will feel in the seat of your pants all the way to redline.
